Driving on a straight road is no problem whatsoever for my 4-vehicle convoy (all AI) moving at a fast pace, much faster than a convoy would normally travel with perfect spacing. Better than I've ever seen human players convoy at that speed, frankly.
When I brought the convoy into Agia Marina, a pretty complex little town, it was able to navigate through pretty well. Considerably better than in A2, where convoys had a bad habit of getting totally messed up on simple turns. Had a hang-up when the convoy was ordered to turn around in place, but they ultimately solved it and got turned around. You may think of Generation Kill...
But, compared to my experiences in A2, I would say the driving AI is a bit better -- or, alternatively/more likely, the maps are now better optimized for the AI, as BI has mentioned.
Arma's AI is quite sophisticated when not artificially limited by bad aiming/spread characteristics and its bad rap is largely from people looking for pop-up target enemies from other games, in my opinion.
